The question who is running for senate in south carolina has become one of the state’s most closely followed political topics as voters prepare for the 2026 election. South Carolina’s U.S. Senate race has taken on added significance following the unexpected death of longtime Republican Senator Lindsey Graham in July 2026. What had initially been a traditional reelection campaign has now become an open-seat contest that is expected to attract widespread attention from both political parties.
The race will determine who represents South Carolina in the United States Senate beginning in 2027. As political parties adjust to the rapidly changing landscape, several candidates have either secured nominations or are considering entering the contest, while election officials continue to oversee the special procedures required after the vacancy.

Why the South Carolina Senate Race Matters
South Carolina has traditionally been a Republican-leaning state in federal elections, but statewide races continue to draw national interest because of their influence on the balance of power in Washington.
The state’s two Senate seats have long been held by Republicans, with Senator Tim Scott continuing to serve in one seat. The second seat became vacant following Senator Lindsey Graham’s passing in July 2026.
Under South Carolina law, Governor Henry McMaster will appoint a temporary senator to serve until the winner of the election takes office. Meanwhile, political parties must determine who will appear on the November general election ballot.
The outcome will shape South Carolina’s representation on major issues including:
- Federal spending
- National security
- Immigration
- Healthcare
- Energy policy
- Judicial confirmations
- Economic development
How the Race Changed in July 2026
For much of the election cycle, Senator Lindsey Graham was campaigning for a fifth Senate term after winning the Republican primary earlier in the year.
His unexpected death in July 2026 fundamentally changed the election. Instead of challenging an incumbent senator, candidates are now competing for an open Senate seat.
An open Senate contest is generally considered more competitive because incumbents typically benefit from strong fundraising, established voter recognition, and organizational advantages.
Political parties are now working through the legal process required to replace Graham on the general election ballot.
Republican Candidates and Potential Contenders
Before the vacancy occurred, Lindsey Graham had secured the Republican nomination after defeating several challengers in the GOP primary.
Among those who had competed in the Republican primary were:
- Calvin Cowen
- Thomas Dismukes
- Patrick Herrmann
- Mark Lynch
- Darius Mitchell
Following Graham’s death, attention has shifted toward who could replace him as the Republican nominee.
One of the first names widely discussed is U.S. Representative Nancy Mace. Multiple reports indicate she is seriously considering entering the race for the open Senate seat, although as of today no official announcement confirming her candidacy has been made.
Additional Republican leaders may also evaluate the race before the party finalizes its nominee. Until official filings are completed, any additional names remain unconfirmed.
The Democratic Nominee
On the Democratic side, physician Dr. Annie Andrews has emerged as the party’s nominee after winning the Democratic primary.
Dr. Andrews is a pediatrician who has previously campaigned for Congress and has built her campaign around several issues, including:
- Expanding healthcare access
- Protecting reproductive rights
- Supporting public education
- Economic opportunity
- Lowering costs for families
Following the unexpected vacancy, Andrews remains positioned as the Democratic nominee for the general election unless state election procedures require additional changes.
Independent and Third-Party Candidates
Several independent and third-party candidates have also qualified or sought ballot access during the 2026 election cycle.
These candidates represent parties outside the Republican and Democratic organizations and provide voters with additional options on the November ballot.
Depending on certification deadlines and election procedures, the final list of candidates may change before Election Day.
Election Timeline
South Carolina’s Senate election follows a structured calendar established by state election officials.
Key dates include:
- Republican and Democratic primaries completed in June 2026
- General election scheduled for November 3, 2026
- Temporary Senate appointment by the governor before the election winner takes office
Because of the vacancy, election administrators are also implementing the legal process necessary to replace the deceased nominee on the ballot.
Campaign Issues Driving the Race
Although the candidate lineup has changed significantly, the major campaign issues remain familiar to South Carolina voters.
Economic Growth
Candidates continue to discuss inflation, tax policy, job creation, manufacturing, and small-business development.
South Carolina’s expanding automotive, aerospace, and technology sectors remain central to economic discussions.
Immigration
Border security and immigration enforcement continue to rank among the most important topics for Republican candidates, while Democratic candidates generally advocate a combination of border security and immigration reform.
Healthcare
Healthcare costs remain a major issue across the state.
Candidates are debating:
- Prescription drug prices
- Rural hospital funding
- Medicare
- Medicaid
- Insurance affordability
National Security
South Carolina has one of the nation’s strongest military communities, making defense spending an important campaign issue.
Military installations, veterans’ services, and foreign policy continue to receive significant attention.
Education
Education funding, workforce training, teacher recruitment, and college affordability remain recurring campaign themes.
How South Carolina Typically Votes
Understanding South Carolina’s political history helps explain why this Senate race is attracting national attention.
Republican candidates have consistently performed well in statewide federal elections during the past two decades.
However, open-seat elections can create different political dynamics compared to races involving incumbents.

Fundraising and Campaign Organization
Running for the U.S. Senate requires substantial fundraising and statewide organization.
Candidates typically invest in:
- Television advertising

Political parties may announce additional candidates or officially nominate replacements where required under South Carolina election law.
